After Uncle Tupelo split, most bets were on Farrar, who had a richer voice, greater mystique, and a hotter new band than ex-partner Jeff Tweedy. But while Tweedy’s restless Wilco evolved, Farrar’s Son Volt stalled and folded. This second solo set is more sketchbook than album, a few lovely tunes scattered over multiple takes and useless tape experiments. And it’s plagued by the sullen uniformity that dogged Son Volt. Just quieter — not a plus.
